Letters latent N 103,595, dated Muy 31, 1870.

IMPROVEMENT IN DITCHING--MACI-IINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: y

Be it known that I, Ronnrrr Fonsr'rn, ot' Clayton, in the county ofHe-ndrieks and State of Indiana, have invented a new and valuable Improvement in Ditchers; andI do hereby declare that the following is a full, clear, and exact description of the. construction and operation of the same, reference being had to the annexed drawing making a partof this specification, and to the letters and Iigurcs of reference marked thereon.

Figure 1 oi' the drawing is a side view of my invention.

' Figure 2 is a top view of the same.

My invent-ion has relation to means for digging ditches, and consists, mainly, in the construction and novel arrangement of a double-acting ditch-plow, a1- ranged to operate backward as well as tin-ward, so that it need not be taken vout of the ditch until it is of the desired depth.

lhe letter A ofthe drawings designates the founda- 'tion beam of my ditcher, having the swell a in the center thereof, and shed .with iron, in the n'ianuer shown.

B B are the supports or inclined side bars, having their lower ends secured to the horizontal beam A,

' and their upper ends mortised together, as shown iu the drawing.

A prop, C, is placed between the meeting ends of the ba-rs B B and the bar A. ,lhs foi-ms a strong and durable frame.

The ditching-bits (t a. are secured to the inclined bars B B, and have the same inclination, except at their lower ends, which have an upward pitch, to give them the proper set to the ground.

rlhe bits are turned up at the sides, thus forming on one side a long ianch, l), ext-ending the whole length of the bit, and on the other a short ilanch, c, only reaching from the point ofthe bit a short distance up th'e main inclination thereof.

'lhe front or cutting-edge of the bit is inclined forward from one side to the other, in order that it may be more easy of operation.

In manufactuling these bits they are til-st made plane. rlhe flanches l) and c are then turned up, and then, after cutting through each anch at the point of bending, the lower end of the bit is vturned up vto the proper angle. rJlhe cut edges of the a-nches are then welded together and linished otf smooth.

e designates a guide, just above the "bit, adjustable by means ofthe bolt d, and arranged to throw out the earth carried up by the bit.

`l) is an adjustable horizontal beam, to which the horses are attached. It is arranged to be secured to the inclined beamsB B by means of bolt-s an.

Series of openings a n are made both in the beams B B and in t-h`e drag-,beam D, so that it can be adiustcd to any height required by the depth of the ditch.

"lhe beam l) consists of two bars s s, arranged one m each side of the frame, and bolted to the sides of the blocks t t at each end. v

l designates the hitching-staple, secured to the bleek t by abolt, which passes perpendicnlarly through the block a little in front of the pivot-bolt which connectsthe block to the bars s. s, and will, therefore, acconnnodate itself to an upward or side draft, or both combined.

'lhe mold-boards Z Z are secured to the drag-beam, and operate to turn away from the ditch the'soil thrown out by the operation ofthe bit a and guide e.

The swell on the bottom ofthe. foundation benin A is designed to incline, whichever end may be for-ward,

a little downward, thus avoiding friction from the parts in rear, and allowing the forward bit to enter the ground freely,

What'I claim as my invention, and desire to secure by Let-ters Patent, is-

1. rlhe double-acting ditching-plow herein described, having a triangular wooden frame, composed of the inclined supports B, horizontal beam A with swell a', and prop C; also, provided with the anched bits a, guides e, and the adjustable drag-'beam D, to which are secured the mold-boards Z, when constructed and arranged to operate in the manner and for the purposes substantially described.

2. The adjustable drag-bar D, composed of the check-bars s, connected at each end by the pivotblocks t, to which are attached the hitching-staples K, when constructed and arranged to operate in either direct-ion, substantially as speeitied.

3. The tbundation beam A, provided with the eentral swell c', when constructed and arranged to operate in the manner as and for the purposes herein set fort-h.

4. In combination with the adjustable drag-beam D andh the adjustable guides'c,tl1emoldboards Z, when constructed and arranged to operate substantially as speeitied.

In testimony that I claim the above I have here-- unto subscribed my name in the presence of t-wo witncsses.
